Flexible notifications for Trac

Description

The AnnouncerPlugin is meant to provide an extensible, user-customizable notification system that can be used to completely replace Trac's default notifications.

At the very least, it will allow users to receive notices about attachments, and to opt-out from receiving messages due to the always_notify_(owner|reporter|updater) options.

The full system (in the not-too-distant-future) will allow users to 'subscribe' to certain events by specifying simple yet powerful rules, such as asking to receive an announcement for any change that involves a ticket with a priority greater then 'high'. Later, a 'watch' feature is intended to replace CC usage, and allow watching of wiki-pages, and then to enable other plug-ins to provide new means for registering messages that users can subscribe to.

The AnnouncerPlugin is meant to be agnostic to what is being watched; where you should send something (email, IRC, jabber, ...), and what format it should look at. All in good time.

I've gone over the various tickets on t.e.o related to notification, and have summarized them at AnnouncerPlugin/Concerns for reference to keep in mind while developing the system.

Example

Initially(very soon now), it'll simply be a drop-in replacement for the default notifications, extending them to include attachment additions and deletions, and allowing users to opt-out from receiving notices normally sent because of the always_notify_* options.
